If you want to build a cooler try 3/4" alum fin radiant heating pipe. The stuf you use to heat your house. When I worked for a compressor shop we built several of these. Just build something like a car radiator and put it in front of a fan. Ours was mounted in the exhaust fan for the shop area. Cooled the shop and the shop air.

In a small shop 1/2 line is plenty and no need for anything larger than 3/4. Most places have one thing running at a time. Simple is good, I have extra piping but really only 5 places I use air, Menard's has one of those tool time kits, regulator, filter, all 1/2 ports under 50$, I threw the oiler away.

Wrong post forum

This should maybe be in the Disussion Forum.

this is one of the points i made before the change and why it was a bad idea. many people ( myself included) don't care what section they are in or are not shore which is the right one.
next we have members telling others they did it wrong or control your self, before long the screw you , bite me starts and we loose members. so let it go, if he wants it here he will post it here. its his question, let him categorize it.
maybe he has a nascar paint booth. painting car's is not motor sports??? i think it is. let others make there own choices.

I'll have to agree. I wander all over these forums. I jump in when I feel like it. I don't care where it is. I suppose the moderator can move the post to the correct area (if necessary). I thought that what a moderator was for.
Thanks, BH

the true Miller moderators prefer to let the board run its self without too much interference. if fighting starts they warn then suspend members as needed. moving posts is not that big a deal and not enough moderators to keep up with them all.
the few member moderators like myself only step in for excessive profanity, nudi ty, and spam. beyond that we leave members posts for miller to handle.
we all just need to let things slide once in a wile and every one will be happy and get along......tall order, i know.

thanks for the help
......or..........
hope i helped feel free to shoot me an e-mail direct i have time to chat.james@newyorkmetalart.comsummer is here, plant a tree. if you don't have space or time to plant one sponsor some one else to plant one for you. a tree is an investment in our planet, help it out.

How would it be to run the 3/4" line but still have that 2x3/8" reducer off the tank?

Enough talk on the PVC, I already know I am going to run copper.

If you stay with the 2x3/8 reducer at the tank your SYSTEM will only flow to the flow potential of the 3/8 reducer. It will not matter how large your downstream piping is.
Change the reducer to a 2x "whatever size piping" you are going to use.

The fitting on the tank will still frow more cfm then the compressor can put out, changing the fitting will not hurt anything, but I don't think you will see any benifit.
The larger downstream piping will act as a receiver storage tank.

I have a similair type compressor, Cambell Halsfield, I will diffinantly build an air system in the new shop (I actually have two of these compressors and will run them in tandom when needed), but for the past 4 years I have just used a 3/8 hose.

I run a 3/8 hose from tank , through the filters to the work 3/8 hose. The sandblast cabinet sucks the compressor down in about six minutes.
Not the ideal setup but I use it this way almost everyday.

not so simple...

Short restrictions in air supply piping do not act as predictably as one may think. The smaller nipple may not play a role under most circumstances. The air is compressed and then finds the pressure/volume on the other side of the restriction until the point that the "choke flow" ratio is reached.

Choke flow calculations are fairly deep into calculus and I certainly am not an expert. What it boils down to is that the pressurre on the downstream side of the restriction would need to be almost half of the supply side before there would be any restrictive effect. I do not think you will experience any problem unless you plan on running multiple high air volume consumption tools at the same time, like a DA and a plasma cutter or impact. You just would not normally use the air fast enough for that to act as a restriction.

That is why most smaller compressors only have a 3/8 outlet.

Of course, to gain the greatest volume and delivery regardless of how quickly the air is consumed, opt for the largest fittings. Easier than trying to do the calculus

I just wanted to point out that some minor restriction may be irrelavant based on the actual use of the system.
